Halfway Between 40 and 137

When you ask "What number is halfway between 40 and 137?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=40 and Y=137.

Halfway Between Line

To find the number halfway between 40 and 137, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 137 into our formula, we get:

(40 + 137)/2 = 88.5

Thus, the number halfway between 40 and 137 is 88.5.

To check that our answer is correct, we subtract 40 from 88.5 and subtract 88.5 from 137 and compare the two numbers:

88.5 - 40 = 48.5
137 - 88.5 = 48.5

As you can see, the halfway number is 48.5 higher than 40 and 48.5 lower than 137. Therefore, our halfway between answer of 88.5 above is correct.
